Repeated addition is a mathematical process of adding equal groups or the same number over and over again. It is a precursor to teaching multiplication and provides a foundation for understanding it. Repeated addition is also known as multiplication, as both methods give the same answer. For example, if 3 is repeated four times, we can either solve it as 3 + 3 + 3 + 3 = 12 or as 4 times 3 = 4 x 3 = 12.

Repeated addition is used to find the total sum of equal groups or repeated quantities. It can be used to solve multiplication problems by breaking down the multiplication into adding the same number repeatedly. For instance, to solve 4 x 3, we can use repeated addition by adding 4 three times: 4 + 4 + 4 = 12. Therefore, 4 x 3 is equal to 12.

Repeated addition is a strategy for introducing multiplication and is used in mathematics education to teach children how to multiply. It is an easier way to combine the same numbers to get a specific amount and helps students link the ideas of addition and multiplication together.
